Li: Dies passt genau damit zusammen dass ein Proton aus zwei Quarks mit elektrischer Ladung +2/3 (genannt Up Quarks) und einem mit elektrischer Ladung -1/3 (genannt Down Quark) besteht und ein Neutron aus zwei Down Quarks und einem Up Quark. In the universe, neutrons are abundant, making upmore than halfof all visible matter. yup. No.of, Q:Assuming that these ions are chlorine-35 .ec_product_added_to_cart a, .ec_cart_checkout_link{ color:#222222 !important; } A proton is one of three main particles that make up the atom. As you might have already guessed from its name, the neutron is neutral. Neutrons stabilize the nucleus, because they attract each other and protons , which helps offset the electrical repulsion between protons. The number 38 is divisible by 1, 2, 19, 38. Die Groe Vereinheitlichte Theorie sagt jedoch seinen Zerfall mit einer Halbwertszeit der Grenordnung 1031 Jahre voraus.
